I was wondering if anyone has pics of any Sub Enclosures that they may have made for a Toyota Tundra < there is Crap for room>. I have a 2003 Extra Cab, I am cutting the floor out under the rear seat passenger side for one 12" Image Dynamics ID Max d.v4, any suggestions would be appreciated =). Right now the plan is to cut and build a sheet metal box that hangs about 8 inches below the cab, that would create enough room to build an MDF enclosure inside of.....anyhow, any pointers would be great, thanks

Make sure you have some kind of skid plate under the box, make sure the sheet metal has been sprayed with rhino lining so it does not suck moisture into the mdf box. I think this is a great idea, I've wanted to do something like this for a long time but I can find no one who will let me carve up the ride, wonder why? Make sure you post some pic's somewhere for us.

Will be taking a lot of pics for this, surely will post a bunch of them. Also trying to come up with a way to make some more room under the rear drivers side seat to drop my 2 Xtants, right now the only place they will fit is one under each of my front seats....unfortunately I can't cut the floor to drop a box on that side because of the gas tank... any suggestions?

I just finish installing a 10" Rockford Sub in my '03 Ext Cab Tundra. I didn't even have to cut a hole in the body. It is under the right rear passenger seat. I just replaced the storage compartent lid with 1/2" mdf, lined the box w/ dynomat, and it sounds great. I also put my amp under the passenger seat. I can email photos if anyone wants.

Ok, Im building a box for a toyota tundra, cutting the floor, making a steel box to drop down below to give me the air space I need for my new sub.... I was planning on building an MDF box to fit inside of this, would it be better to just use fiberglass?, would save me about .25 of an inch all the way around except for the top of the enclosure... let me know! ~Jay

I am currently building a fiberglass box to fit in that same compartment. (without cutting out the floor) Just have to match up a sub for the airspace. Will send pics if you are interested ------------- if its jammed force it - if it breaks in the process it needed to be fixed anyway

would love to see it,... that was my first thought, to build the enclosure into that space,, I was going to go with one JL 10w3, with a little effort it seems that would do decent that way. Getting the proper space for my 12" ID Max Dv.4 is getting to be a real pain in the ass. with the way the frame and crossmember sit under the passenger side of the vehicle. Also Limited because of the seat belt mounts, then towards the middle, the Heat Shield.......anyhow, wouldn't be as much fun without all the snags =) Send me those pics when you get the chance... RZrogue@yahoo.com Thanks, ~Jay

I'm thinking I'm going to use the Phase 2 Punch 10' sub. It's shallow enough to mount and minimum airspace is like .35c/a or close to that. The box I'm building only has .45, so it should be a hard tight sound. Especially in a small truck cab. I will get pics to you next weekend. ------------- if its jammed force it - if it breaks in the process it needed to be fixed anyway

I'd use MDF, but that's mainly because I don't know anything about fiberglass! :) There is a fiberglass forum here on the12volt.com, have you checked it out? ------------- Support the12volt.com

I know this may be shocking for a lot of you guys but building some stupid sub enclosure for the backseat storage compartment made of fiberglass or mdf is stupid. Just layer the metal box with dynomat and put some foam in the channel that connects the two compartments and it sounds great. The box is aleady lined with noise reducer and that way you have built in ports.

I disagree completely. What you'll end up with is a flexing, not-necessarily air tight, booming, unstable enclosure. I've tried building enclosures out of sheet metal and they just don't work. They resonate like mad even with dynamat and even using 60 gage stainless steel. I even tried coating the inside with roofing tar to dampen the vibrations, and no luck. The constant flex destroyed all enclosure parameter calculations giving very unpredictable response curves that changed over time as the enclosure flexed and bent and heated up and developed air leaks, etc etc etc. It was a bad experiment. There is no substitute for MDF. ------------- Support the12volt.com

First off for my project, there is NO way to fit the sub I am using into the storage compartment without cutting... just not going to happen. As for the fiberglassing, I have not used it before, but I was thinking that with the space that I do have available to use, even after the cut and drop box that I may save a little more space being that the fiberglass' thickness would be around 1/4 less... not sure how the resonance would be in such an enclosure though =/.

I think that it is funny that I am being told that placing a sub in that compartment won't work when that is what i did and I have pics to prove it. The compartment is not like regular sheet metal since this metal is folded and bent to make it stronger. O well here is a pic for those non believers. -------------

Fiberglass is not as hard as it looks. It's just time consuming. This box will be espcially easy since the top is all that will be showing. I can talk you through the proccess if you like? ------------- if its jammed force it - if it breaks in the process it needed to be fixed anyway

That would be great robbie, thanks ! and btw Tipp, nobody said that it would NOT work as in its impossible to stick a sub in that enclosure, what was meant by that I believe is that A) there is NOT the correct airspace doing it that way, NOR is doing it that way going to give you a solid enclosure. Its sort of like Putting tires that are too large on your Vehicle without installing the proper lift, they may fit, but you may not be able to steer anymore =) ~Jay

And I agree with both of you.. There is a right way to do things, the assumed correct and OK way to do things and the wrong way to do things, which of the above do you think pertains to you?

tippman, nice looking install. and thanks for the info man. I am just going for a different look with a gelcoat finish. And I have spent much time setting up the rest of the truck cab for SQ. I'd hate to stop at the sub if ya know what i mean ------------- if its jammed force it - if it breaks in the process it needed to be fixed anyway

I would Def look into fiberglass, not only does it look a ton better but it will help you get every bit of air space u need with that small of room

dream it, build it, fiberglass it
